Panasonic Cube Ac
Manufecturing defect

I have purchased A.C on 23/05- They came & installed it but didn't checked it. when i was using it, it was not cooling only. after a series of calls they came & checked on 25/05. but was unable to tell the appropriate reason, in evening of 25th another person came after several calls.& told that ac have manufacturing defect, they said that they will replace it but not yet replaced. as there was manufacturing defect it should be corrected by that day only any how, i contact Mr.pankaj one of representative of Panasonic India in ranchi.i got only false commitment and assurance only, now i m irritated from all these false things .i need result and compensation against my time loss and warranty date loss.
